Swap out a whining or stuck climate control with the Dorman blend door actuator (P/N:604-211), a direct-fit replacement for the 2002-2010 Ford Explorer, 2003-2005 Lincoln Aviator, and 2002-2010 Mercury Mountaineer. This is the AUXILIARY-position actuator: it drives the blend door that regulates airflow through the HVAC case, so if the original auxiliary actuator has failed, this Dorman air door actuator replaces it and is designed to move that door again.
Direct replacement: engineered to drop in like the factory air door actuator on the listed applications and functions.
Position specific: many vehicles use several HVAC door actuators for different locations and functions — review the application notes to confirm this matches the actuator you need to replace.
Durable construction: designed and tested to strict standards to help resist wear and electrical burnout for reliable operation.
Backed by experience: supported by a team of experts and engineers in the United States.
Because these platforms can carry multiple actuators, this Dorman hvac heater blend door actuator covers the auxiliary position; verify the position notes before ordering. See the "Vehicles it fits" section for engine-level fitment.
